Tyler ran as a National Democrat, until he saw he wouldn't win, and withdrew.

Smith, after dying of bullet wounds at the Liberty Jail in Carthage, saw his campaign end abruptly. No record indicates if his running mate, Sidney Rigdon, tried to make any effort at the polls.

The hopes of the Whig Party for a reform of the federal government ended when President William Henry Harrison developed pneumonia on his inaugural day in 1841 and died after just one month in office. VP Tyler became the first acting President. Tyler showed his independence from the Whig Congress by vetoing a bill to replace Van Buren’s subtreasury system with a new national bank. All of Harrison’s cabinet resigned save Daniel Webster, the Secretary of State, and the Whig Party read Tyler out of the Party.
As 1844 began, the two parties looked forward to a contest between Henry Clay and Martin Van Buren. President Tyler, not yet ready to concede defeat for a second term, prepared a treaty to annex the independent Republic of Texas. Both Clay and Van Buren opposed annexation and insisted that the treaty would bring about a war with Mexico. Tyler appealed to the south, where support for annexation was more widespread. Democratic delegates spurned Tyler and supported Lewis Cass at their national convention. The Democrats finally chose James Polk, former Speaker of the U.S. House, who advocated annexation. Tyler withdrew from the race rather than split the annexation vote.

Polk won a narrow victory over Clay. The critical state in the election was New York; the large vote for the Liberty Party there came primarily from Clay supporters and tipped the scales to the Democrats.
